Akuflex-Super

Akuflex-Super is a flexible environmentally friendly soundproofing material. It is recommended for use as an elastic layer in the construction of ‘floating’ floors, as well as a substrate for finish flooring.

Applications

Akuflex-Super fabric is used as an elastic spacing layer under the leveling screed in soundproofing floor structures, as well as a compensating soundproofing substrate under finish flooring such as laminate or natural parquet boards.

Composition

The material is made of 100% polyester fiber with a propylene film coating. It is manufactured in accordance with TU 23.99.19-007-28789041-2019.

Features

• Universal application: under leveling screed and/or finish flooring.
• The polypropylene film coating acts as a separating layer and allows to lay the screed and the finish flooring directly on the material.
• The fibrous structure of the material guarantees stable high acoustic performance throughout the entire service life.
• Akuflex-Super increases the service life of the finish flooring due to microcirculation of air and moisture and protects from the effects of residual moisture of the leveling screed.
